In order to produce a printing line, the portionv of the band between the pins 1 and 8 into which the inscriptions have been impressed, is suitably placed in a mould consisting of the members II, I2, I3 and I4. The mould members Il and I2 which extend parallel to theaxis of the band are pressed tightly against the lateral edges I5 of the bridge members 2. Thereafter molten wax or lead is poured on to the mould consisting of the mould members II', I2, I3 and I4 and the band I, so as to form the cast I6 and after the wax or lead has suitably hardened thev band and the mould members are removed and the hardened wax or lead mass provides'a standard length positive printing line.

I claim:v

1.' The herein described method of forming and justifying printing matrix bands, which comprises forming spaced groups of impressions on a band of inelastic non-rigid material, providing incisions therein marking the beginning and'end of a line, respectively, bending the portions of the band between spaced groups of impressions outwardly beyond the normal plane of the' band to bring the parts of the band carrying the impressions more closely towards one another, thereafter causing the band to travel, engaging the band at an incision marking aline end, while the remaining partv of the band continues to travel, wherebysaid bent parts of the band are more or less attened and said groups of impressions are spaced apart, and engaging the moving band at an incision marking the other line end, when the band has attained the length of a line of type.

2. A method of the character described, which consists in the steps of imprinting upon a band, marginally notching said band and thereby forming bridge members between spaced groups of impressions, bending said bridge members and 4moving said spaced groups of impressions towards one another, spacing Isaid groups of impressions apart to vjustify the band, and thereafter placing the, extended band in a mold and pressing -the bottoms of the side walls thereof tightly against the surface of the band and the sides of the said walls against the edges of the said bridge members..l

3. The herein described method of forming and justifying printing matrix bands, which comprises forming spaced groups of impressions upon a band of inelastic non-rigid material, bending the material of the band between said groups outwardly beyond the normal plane of the band to bring the parts of the band carrying vsaid groups into closer proximity to one another, more or less flattening the bent-out portions of the band to space said groups apart and thus justify said band, placing said band in a mold and tightly retaining the band in said mold.
